Banning butane hash oil in the city of Detroit? Only Warren’s crazy Mayor Fouts would try that.

Language contained in the definitions of both the Licensing (Sec. 24-13-2) and the Zoning (Sec. 61-3-353) portions of Detroit’s proposed dispensary ordinance defines what marijuana is, and they both include the statement: “This shall not include butane hash oil.”

Normally banning anything related to marijuana use would be a legal no-go. The Michigan Medical Marihuana Act’s supremacy clause overrules local zoning ordinances (and the Michigan Home Cities Rule Act and state forfeiture laws) which would make any ban on marijuana null and void, but a Court of Appeals decision in a case known as People v Carruthers changed that protected status for concentrates and edibles.

Butane hash oil is a concentrate derived through an extraction process whereby cannabis flowers are washed with gaseous butane to separate the valuable healing oils from the tarry, rough plant material. Only the useable oils are harvested, and the butane is slowly released from the oil over a period of time in a process known as ‘purging.’ Once the butane is fully purged from the oil it is ready for human use in topical creams, liquid tinctures, various foodstuffs and the like.

Since BHO is a concentrate it is controlled via the Carruthers decision. So its current status is banned, therefore not deserving a special mention in Detroit’s ordinance.

SAN DIEGO (AP) -- Authorities seized 12 tons of marijuana and arrested 22 people after discovering one of the longest cross-border tunnels between the U.S. and Mexico, officials said Thursday.

The passage connecting warehouses in San Diego and Tijuana, Mexico, was about 2,400 feet long and 30 feet deep. It was lit, ventilated and equipped with a rail system - hallmarks of the most sophisticated tunnels found along the border.

Near-simultaneous police stings on Wednesday resulted in six arrests in San Diego and 16 in Mexico. Authorities recovered two tons of marijuana in the U.S. and 10 tons in Mexico.

U.S. authorities said smugglers tried to move the first load of drugs through the tunnel on Wednesday but that nothing got through undetected.

The sting came after an undercover agent for U.S. Homeland Security Investigations agreed to provide the drug smugglers with drivers and use of a warehouse in exchange for a $10,000 payment for each truckload of drugs moved, according to a probable cause statement.

A record number of Americans think marijuana use should be legal, according to a new poll released Wednesday by international pollster Gallup.

And government surveys published Wednesday offered further indications that marijuana is moving into the mainstream nationally, nearly three years after Colorado voters legalized recreational pot.

Marijuana use among U.S. adults doubled over the past decade, rising to more than 22 million mostly recreational users, the surveys show.

The results come from a comparison of health surveys from 2001-02 and 2012-13 sponsored by the National Institute on Alcohol Abuse and Alcoholism. Almost 80,000 adults aged 18 and older participated in face-to-face interviews about various health-related behaviors, according to results published in the journal JAMA Psychiatry.
